ALMA Detection of Bipolar Outflows: Evidence for Low Mass Star Formation within 1pc of Sgr A*
F. Yusef-Zadeh, M. Wardle, D. Kunneriath +3
We report the discovery of 11 bipolar outflows within a projected distance of 1pc from Sgr A* based on deep ALMA observations of CO, H30 and SiO (5-4) lines with sub-arcs…
Nuclear Activity and the Conditions of Star-formation at the Galactic Center
A. Eckart, M. Valencia-S., B. Shahzamanian +15
The Galactic Center is the closest galactic nucleus that can be studied with unprecedented angular resolution and sensitivity. We summarize recent basic observational results on Sa…
Molecular gas in the immediate vicinity of Sgr A* seen with ALMA
Lydia Moser, Álvaro Sánchez-Monge, Andreas Eckart +9
We report serendipitous detections of line emission with ALMA in band 3, 6, and 7 in the central parsec of the Galactic center at an up to now highest resolution (<0.7''). Among th…
ALMA and VLA observations of emission from the environment of Sgr A*
F. Yusef-Zadeh, R. Schödel, M. Wardle +6
We present 44 and 226 GHz observations of the Galactic center within 20 of Sgr A*. Millimeter continuum emission at 226 GHz is detected from eight stars that have previously bee…
Plunging neutron stars as origin of organised magnetic field in galactic nuclei
V. Karas, O. Kopacek, D. Kunneriath +4
Black holes cannot support their own internal magnetic field like, for example, compact stars can. Despite this fact observations indicate that event horizons of supermassive black…
Tidal Distortion of the Envelope of an AGB Star IRS 3 near Sgr A*
F. Yusef-Zadeh, M. Wardle, W. Cotton +4
We present radio and mm continuum observations of the Galactic center taken with the VLA and ALMA at 44 and 226 GHz, respectively. We detect radio and mm emission from IRS 3, lying…
